Open Inventor练习-文件存储

Open Invenor采用SoWriteAction或SoOutput写三维数据格式到文件，如下是具体实现。

#define COIN_DLL  #define SOWIN_DLL  // 加载COIN库文件  #ifdef _DEBUG  #pragma comment(lib, "SoWin1d.lib")  #pragma comment(lib, "Coin3d.lib")  #else  #pragma comment(lib, "SoWin1.lib")  #pragma comment(lib, "Coin3.lib")  #endif  // 添加COIN头文件-Window操作显示库和节点库  #include <Inventor/Win/SoWin.h>#include <Inventor/Win/viewers/SoWinExaminerViewer.h>#include <Inventor/nodes/SoCube.h>#include <Inventor/nodes/SoDirectionalLight.h>#include <Inventor/nodes/SoMaterial.h>#include <Inventor/nodes/SoPerspectiveCamera.h>#include <Inventor/nodes/SoTransform.h>#include <Inventor/nodes/SoSeparator.h>#include <Inventor/actions/SoWriteAction.h>int main (int argc, char** argv) {HWND win = SoWin::init(argv[0]);if (win == NULL) exit(1);SoSeparator* root = new SoSeparator;root->ref();SoMaterial* mSilver = new SoMaterial;mSilver->ambientColor.setValue(.2f, .2f, .2f);mSilver->diffuseColor.setValue(.6f, .6f, .6f);mSilver->specularColor.setValue(.5f, .5f, .5f);mSilver->shininess = .5;root->addChild(mSilver);root->addChild(new SoCube);SoWriteAction wa; wa.getOutput()->openFile("test.iv");wa.getOutput()->setBinary(FALSE);wa.apply(root);wa.getOutput()->closeFile();SoWinExaminerViewer* x = new SoWinExaminerViewer(win);x->setSceneGraph(root);x->setTitle("foo");x->show(); SoWin::show(win);SoWin::mainLoop();return 0;}
